The present invention relates to an inner-type connecting structure of a bulb assembly which includes a bulb holder having a pair of side connecting slices with inner hook at the end. A pair of solts are provided on the supporting object for engaging with the slices. So the bulb assembly is fixed and positioned, meanwhile the engagement between the bulb holder and the supporting object is firm and secure.
1. An inner-type connecting structure of a bulb assembly including a holder with a bulb assembly thereon and a pair of side slices for engaging with a supporting object; and the characteristic is that:
the slice being provided with an inner hook at the end and a pair of slots being provided on the supporting object relating to the slices; in order that the inner-type connecting slice is capable of being engaged within the slot easily and firmly.
 Referring to the FIGS. 3 to 5, the present invention includes a bulb holder (1) with a bulb assembly (4) thereon. A pair of inner-type connecting slices (5) are provided on a side of the bulb holder (1) and each of the slices (5) has an inner hook (51) at its end. The supporting object (6) is provided with two slots (61) which are related to the two slices (51). So it will be very easy to insert the slices (51) into the slots (61) to obtain a secure connection and the bulb assembly (4) is positioned at the same time.
 As shown in FIGS. 6 to 8, the inner-type connecting slices (51) are made of plastic material with flexibility. When the slice (51) is inserted into the slot (61), it can be bent outward slightly, as in FIG. 7. When the engagement is completed as in FIG. 8, the slice (5) is recovered and the inner hook (51) will provide a stable connection. Due to the hook (51) in provided inward, the engagement will be firm and secure between the holder (1) and the supporting object (6) that prevents from separation when it is collided in accident.
 The improved structure of the present invention is obviously novel and effective. Thus it has excellent practical value in the field. Evidently the invention has the essence of a patent. We hereby apply for a patent grant.
FIG. 1 is a perspective view showing a bulb assembly to be engaged with a supporting object of a prior art structure.
FIG. 2 is a perspective view showing a bulb assembly to be engaged with a supporting object of another prior art structure.
FIG. 3 is an exploded perspective view showing a bulb assembly according to the present invention.
FIG. 4 is a perspective view showing the bulb assembly to be engaged with a supporting object according to the present invention.
FIG. 5 is an assembled view of FIG. 4.
 FIGS. 6-8 are plan views showing the engaging movements as being assembled of the connecting slices with the supporting object.
 There are different connecting structures as shown in FIGS. 1 and 2, for fixing a bulb assembly on a supporting object. In FIG. 1, a pair of outer-type connecting slices (11) are provided on a side of the bulb holder (1) to be engaged with an aperture (13) of a supporting object (12). In FIG. 2, a ring (2) having a pair of outer-type connecting slices (21) is provided around the bulb holder (1). The connecting slices (21) are engaged within an aperture (31) on a supporting object (3) and then the bulb (4) on the bulb holder (1) is fixed on the supporting object for decorative purpose. The above said connecting structure is without stable connection and is very possible to be loosed when the bulb assembly is collided in accident.
 Accordingly, the primary object of the invention is to provide an inner-type connecting structure of a bulb assembly to fix the bulb on a supporting object firmly and to increase the strength of engagement. Now the features and advantages of the present invention will be described in detail with reference to the accompanying drawings.
